. To all whom it may concern l' ings, forming a part l This invention relates to improvements Ain y Be it known that I, Gannon A. Jonsson, a citizen 'of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railway-Car llfrat- Riggings, of which the following is a full, clear, concise, Aand exact description, reference being had to the accompanying draw- Iof this specification.

y railway car draft riggings.

' devices, as herein -shown,

" being et thefront and is prevented from able in said slots.

tia-lly cylindrical to Aat An object of the invention is to provide a draft rigging for railway cars which is in the nature of a combination friction and spring gear and in which an easy draft action is rovided.

The` invention improvements in in the novel combinations of the parts and described or furthermore consists in the claimed.

In the drawing forming a part of this specification, Figure 1 is a vertical ,sectional view of a draft rigging embodying my' imhorizontal sectional provements.y Fig. 2. is a view taken on the line 2 2 of Fig. 1 and full but?. Figs. 3

showing the gear under and 4 are verticalv sectional views taken on the lines 3f?) and lr-l respectively of Fig. l and Fig. 5 is a view, 'similar to Fig. 2,- but showing the parts under full draft. t

In said drawings, 10Q-10 denote ,the .center or draft sills eachof which' is provided with three elongated slots 11 receiving a movable key 14; the slots 12 a movable key 15 and the slots 13 a Inovable coupler key 16. Mounted between the sills and on the keys 14 and 15 is an elongated combined lriction cylinder and spring casing 17, the friction cylinder portion 18 the spring casing portion 19 at the rear. Said friction cylinder and casing is'provided with slots at the rear through which passes theukey 14 and longitudinal movement Said members are also provided with additional elongated slots Q1 at the' front thereof through which extends the key also longitudinally mov- The'keyslet and 15 also pass through slotted rear and front followers 22 and 23 respectively which are substanthef cylindrical shell 15, the latterbeing Specification of Letters Patent.

the parts and devices and slots 11, 19. and 13, the A that the springs are and casing.'v Mounted between said follow-` ers are nested springs 2l.

Within the aimes Shen portion is is mounted any suitable friction device and, as y shown, the same consists of a plurality ol2 friction slices 25, 'wedge Q6, anti-friction 32, 'each side link.

The operation lows z-In normal position of the parts key 16 is positioned centrally Within slots 13;- the key 15 at the Slots 12; and the key 14 'at the the .draw bar, the wedge and friction shoes are resisted by the nested s front follower V23,' w 'ch is moved rear- I'Wardly with the key 15. During thismovement, the shell 17 is of the device is as olprevented from rear ward movement, as is also the rear follower front ends of the; the rear end oftflygl, the slots 11.- Upon inward movement 'of the' operated thereby and movement thereof is ,r

The links 32 however. pull `the rear key 14: forwardly and vthus the shell 17 and the rear follower 22 so at the same time providing suliicient .caggg pacity under bud.
